iDrive not recognizing Iphone 4
I hope this is the correct section for this question. About a week ago, my M3 stopped recognizing my Iphone 4 when I plugged it into the auxiliary/USB cable in the center console. When I plug it in and scroll over to the auxiliary tab, it does not bring up my music as usual but it still charges my Iphone. In order for it to play music, I have to go to the music app and press play to get the musci to play through the car speakers. Once it's playing, the up and down arrows on the steering wheel no longer change the song and the i Drive still does not detect my Iphone 4. My friend who has a 335i said that his car did the same thing when it was time for a software update. I have a 2008 M3 that just went out of warranty a little over a month ago. What is causing this issue?
Thanks in advance
